Title: Fabric cutter and method
IPC: B26F1/38
Filed: 1973-11-21
Abstract: 1451485 Cutting apparatus E D ESTEPHANIAN 21 Nov 1973 54031/73 Heading B4B [Also in Division B3]  Apparatus for cutting a piece of a given shape from a length of sheet material, e.g. fabric, comprises a cutting station 5 and means 14 for feeding the sheet longitudinally thereto in a stepwise manner, the cutting station including two rows of independently-actuatable blades 10a and 11b, and means for actuating selected blades each time the sheet pauses during its stepwise movement, the arrangement being such that cuts made during succeeding pauses join together and define the periphery of the piece which is progressively severed from the sheet. As shown, two rows of blades 10a and 11b are movably mounted in their respective cutter heads 10 and 11, the rows extending across the full width of a material support table 2; the blades 10a and 11b co-operate with mating die slots 13a and 13b respectively formed in a bed 12. The blades are actuatable individually and independently from drive means located in a housing 15; the cutter heads 10 and 11 and the die bed are both laterally movable so that a selected blade and mating die can be used successively for each increment of movement of the material in order to cut a continuous cut. The actuation of the blades is controlled by a computer 16 which is programmed such that the selected blades cut a particular shape from the material. The material which may be synthetic or natural fabrics or metal, may be drawn from supply rolls 7a-7g by feed rollers 4, 5 and is incrementally fed past the cutting station S by two rows of pairs of jaws 116, 119 and 117, 120 located above and below the material. In operation, the sets of jaws close on the material, Fig. 3, and are then moved to feed the material one increment of travel. While still maintaining their grip and holding the material under tension, the selected blades are actuated to cut through the material. The blades are then withdrawn and the jaws again actuated to feed the material a further increment. As shown the blades are angularly arranged such that the periphery of the cut-out piece is formed with a series of notches thereby preventing unravelling of the weave. Alternatively, the blades can be arranged such that the edges of the cut-piece are formed by straight lines, Fig. 14 (not shown).

The outer element may be planar, comprising, for example, an automobile dashboard or an aircraft control panel, but in the embodiment shown the outer element 3 is also tubular. Frictional engagement between the tubes 1-3 is arranged Fig. 3 (not shown), so that, with outer tube 3 held stationary, inner tube 1 may be rotated without moving intermediate tube 2, whereas rotation of tube 2 automatically causes corresponding rotation of tube 1. The index lines shown comprise helical lines A and B on tubes 1 and 2 and a straight, logarithmically-graduated line C adjacent window 7 of tube 3. Multiplications can be made by effectively adding lengths of line C. In a first modification, Fig. 4 (not shown), the two helical lines (and not the straight line) are logarithmically graduated. In a second modification, Fig. 5 (not shown), tubes 1 and 2 bear straight, logarithmically-graduated lines, whilst tube 3 bears a helical line. In a final modification, Fig. 6 (not shown), tube 3 bears a straight, linearlygraduated line, whilst tubes 1 and 2 each bear a curved line shaped according to a logarithmic function of the values on the line borne by tube 3. The window in tube 3 may include a magnifying glass. A luminous source may be provided inside tube 1, the latter then being transparent or translucent. The device may be incorporated in a pencil, pen or tool handle.
